What value for inductor Q is achievable in integrated RF ?

it varay from 5 to 10 at max ,

khouly

for on chip inductor

We have achieved 25 with copper metal layers..
But normally it should be around 5-15 with standart processes

is think this copper metal is very high from the sybstarte , maybe it the 8th layer ,

khouly

at what frequency ?
above metal 8 ?

The maximum of the Q at approx. 2 GHz (ifI remember right)

cacomment on the control voltage range say for 1.8 v Vdd and using diff.arch
